The Bahraini Dinar was introduced as a currency in 1965, six years before Bahrain gained full independence; it replaced the Gulf Rupee at a rate of 10 rupees = 1 dinar. The Dinar is subdivided into 1,000 Fils (the singular form is also Fils); hence it is usually represented with three decimal places denoting the Fils. The 100 Fils (0.100 Dinar) coin is a relatively small denomination.
The 1965 issue coins were larger in diameter and were made from cupronickel (copper-nickel alloy); there was also a commemorative silver coin of the same type in 1983. In 1992 this was changed to a slightly smaller bimetallic coin (copper-nickel centre and a brass outer ring) with a different design. Some silver 100 fils coins have also been issued as non-circulating legal tender.
